Holding Brake chatter on V2 @ SFGAm on 11/3

Saturday, November 9, 2002 8:26 AM
While riding V2 this past weekend, I noticed a lot of brake chatter during the brief hold on the back spike. The feeling was a lot like the pulsing you get when your car's ABS (anti-lock brake system) activates. I felt it really took away from the fun of the hold. My only theory on it, aside from potential maintainence problems, is maybe the fact that the magnetic hold was calibrated for a full train while my brother and I were the only riders during our runs.

Anyone else notice this on V2??? On any other Impulse??

When I was on V2 on 11/3, I didn't notice that but what I did notice was that while getting launched, the LIMs were clattering and makinf very loud and funny noises like it was about to fall apart. When I went on V2 in the summer, it did not make these noises.

probably due to the temps I'd imagine.

Maybe, S:UE didnt make that sound and the temp was right around 30 degrees, sounded like it always did and gave a great ride.

It wasn't just noise, but a noticeable shake/vibration, too.

V2 did that when I was there a couple of weeks before SRM, and when I was at GAm again a few days after. It was really noticable, and I found it odd, especially considering that SUE doesn't really do it at all.

When the brake on V² at SFMW is on, it chatters as well.... It just kind of "lets" you down. Interesting.

The reason V2 at SFMW does this is because people complained about the brake and how it "thrust" you into the restraint. In fact the holding brake was only at full power for roughly a week. Now it brakes-lets go-brakes rapidly, providing some feeling of deceleration but not throwing you around at all.

I would suspect the same thing on GAm V2.

It's too bad, though, but it's no excuse. The ride was designed with this action in mind. I don't mind the bruises... In fact, after 5 trips on V², I was quite black and blue for the remainder of my SoCal trip. I still long for S:UE. It is quite a bit more intense, if I recall correctly.:)

Well for the people who have not been on the coaster with a full power hold, they are fine and content. As more me I get off everytime thinking about how screwed up it is that they don't use the brake well.

Infact, from certain angles you can see the train goes higher on the first rear launch than the second. It is somewhat sad.
